opencv--'numpy.ndarray' object has no attribute 'read'

练习图像匹配，python3.6，使用 Image.open(screen,mode=“r”)打开图片失败，报错’numpy.ndarray’ object has no attribute ‘read’

import cv2,os
from PIL import Image

base_path = os.path.join(os.getcwd(), 'src')
screen= cv2.imread(os.path.join(base_path,"screen.png"))

def compare():
    # standard = cv2.imread(os.path.join(base_path,"screen.png"))
    pice = cv2.imread(os.path.join(base_path,"pice.png"))
    result = cv2.matchTemplate(screen,pice,cv2.TM_CCOEFF_NORMED)
    min,max,minLoc,maxLoc = cv2.minMaxLoc(result)
    print(min,max,minLoc,maxLoc)
    print(pice.shape)
    pos_x = maxLoc[0] + int(pice.shape[1] / 2)
    pos_y = maxLoc[1] + int(pice.shape[0] / 2)
    if max > 0.8:
        return pos_x,pos_y
    else:
        return 0,0


def getCut():
    img = Image.open(screen,mode="r")
    w, h = img.size
    print(w, h)
    # newScreen = img.resize(())

if __name__ == '__main__':
    getCut()
    # x, y = compare()
    # print(x, y)
    pass

遇到问题 Assertion failed (corrsize.height <= img.rows + templ.rows - 1 && corrsize.width <= img.cols + templ.cols - 1)
